SPECIFICATION forming part of Letters Patent No. 477.989, dated June 28,1892.

Application filed January 11, 1892. Serial N... 417,718. (No model.)

To all whom. it may concern.-

Be itknown that we,W1LLIAM H. CALLAWAY and CHARLES C. WVEST, citizens ofthe United States, residing at San Angelo, in the county 5 -of Tom Greenand State of Texas, have invented certain new and useful Improvements nCar-Couplers; and we do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing bad to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

' This invention is in couplers adapted to use a link of ordinary formand to be so set that coupling may be automatic or not, as desired.

In the drawings, Figure 1 is a side elevation of the coupler. Fig. 2 isasection on the line 2 2, Fig. 3. Fig. 3 is an end View looking in thedirection of the arrow of Fig. 2.

Referring to the drawings, the draw-head A is provided with the usualaxial opening having a bell-month so formed that an approaching link maybe guided by the inclined sides into the middle of the opening. Averticallysliding coupling-pin B, projecting downward from a head 0,resting normally upon the draw-head, moves in an aperture extending 3oentirely through the draw-head and engages the link in the usual manner.A web D, projecting downward also from the same head,

rests normally upon the inner end of the link when the latter is inposition and prevents the outer end from sagging downward whenunsupported by an adjacent head. A bar D,

parallel to the coupling-pin, extends downward at the rear edge of theweb. It is longer than the pin and at all times projects 4 below thedraw-head, where it is provided with a nut or apin F, that by meetingthedraw-head limits the upwardmovement of the bar, pin,

and web. This limit is so fixed that the upward motion is arrested assoon as the lower end of the pin is above the axialor link openingin thedraw-head. The upper part of the draw-head is slotted between the barand pin to receive the web; but below the plane of the link there arebut the two disconnected aper- 5 tures for the pin and bar. Upon eachside of the draw-head and a little in front of the plane of the pin is alug G, whose upper face preferably inclines slightly forward, and uponeach side of the head 0, at points vertically over the lugs, is pivotedan arm H, whose rounded lower end rests upon the corresponding lug whenthe pin is near its highest point. The arms when in this position holdthe pin raised above the path of the link. Just in front of these armsarevolublero'd I passeshorizontally through the draw-head at the upperside of the link-aperture. At the outer ends of this aperture aredownwardly=extending arms J, lying alongside the arms H, and at middleof the rod is a third arm J in the same plane as the others, obstructingthe linkopening. Now when the coupling -pin is raised above thelink-opening in the drawhead and supported by the arms I-I, resting uponthe lugs G, the apparatus is ready for automatic coupling, and ifanother car with the usual projecting link be brought to position forcoupling the link is guided by the sloping walls against the arm J,which it swings rearward as it passes rearward beneath the end of theraised coupling-pin. The displacement on the arm J rotates the rod I andswings the arms J, pushing the arms H from their supporting-lugs andleaving the coupling-pin and connected parts free to fall under theforce of gravity, aided, if desired, by a suitable spring. As the linkthus descends, it passes through the link, and the coupling is complete.

For uncoupling, the pin is raised, preferably by a chain K or the likesecured to the head and connected with well-known devices upon the car,operable from either side or from the top of the car to temporarilyraise the chain. When the parts are so raised, the arms H, be- 0 ingpivoted vertically over the lugs, swing forward as soon as they pass thelugs and rest upon the latter as soon as tension upon the chain ceases,again supporting the whole in position for automatic coupling. 5

As shown, the arm J is made V-shaped and its point-extends slightlybelow the plane of the link and swings in a slight groove in the floorof the axial opening. As soon as the end of the entering link passesthis point the lattoo ter falls between the side bars of the link,which'it tends to adjust laterally; but it offers ing the pivots for thearms H.

no obstruction to the withdrawal of the link, since there is nothing toprevent its swinging forward. We prefer to make the rod and its armsreadily removable, and with this object the end of the draw-head isslotted inward at L to form the rod-bearing, and the rod is rev tainedin place by a band M, lying in agroove in the sides of the head andhaving its lower ends connected by a rod N. The swinging arms H arepreferably retained in their proper path by loops 0 upon the sides ofthe drawhead. i

As the coupling-pin receives great strain and wear, it is advisable toprovide for its renewal before the other parts are materially worn. Tothis end it is not made integral with the head 0, but has a smaller head0' of its own,which fits a slot in thelargerone and is retained bysuitable devices, preferably a bolt P, passing through both heads andform- What we claim is' 1. The combinatiomwith the draw-head having lugsupon each side of the same, of the vertical coupling-pin, the pivotedpin-supporting arms arranged to contact with the lugs, and tripping-armsadapted to be operated by the centering-link and throw the arms from thelugs, substantially as shown and described.

2. The combination,with the draw-head having side lugs, of thecoupling-pin having a head, supporting-arms pivoted to sides of head andadapted to rest upon the lugs, and atransverse rock-sh aft carrying acentral operatingarm and the side tripping-arms, all adapted to operatesubstantially as shown and described.

3. The combination, with the draw-head, of the coupling-pin, the bar,and the web, all secured together and sliding vertically in thedraw-head, the pivoted arms arranged to support said sliding parts whenresting upon projections upon the draw-head, and the transverserevoluble rod provided with the central arm obstructing the linkopeningin the drawhead and with end arms operating to displace saidsupporting-arms when the central arm is swung inward by the enteringlink.

4. The combination,with the draw-head slotted at its mouth, of thetransverse rock-shaft journaled and carrying the operating and trippingarms on said slot, the retaining-band, the coupling-pin detachablysecured in its head, and the supporting arms and lugs, all arrangedsubstantially as shown and described.

In testimony whereof We afiix our signatures in presence of twowitnesses.-
